Hundreds of Christians, Jews and Muslims came together at the Tower of David in Jerusalem to sing Bob Marley's "One Love" in Hebrew, English and Arabic.

Koolulam is a social-musical initiative, centered around mass singing events, attended by non-professionals, promoting the idea that musical harmony can inspire harmony in humanity.

Koolulam was established with the goal of bringing together people from all walks of life.

On June 14th, 2018, in honor of the historical visit to Israel by Indonesia’s religious leader Sheikh Haji Yahya Cholil Staquf, Koolulam invited 1000 people who had never met before to a special event at the Tower of David in Jerusalem, to sing one song, in three languages and in three-part vocal harmony. The event was produced in conjunction with the Tower of David museum and Jerusalem.Com.
